اللَّهُمَّ رَبَّ جِبْرَائِيلَ وَمِيكَائِيلَ، وَرَبَّ إِسْرَافِيلَ، أَعُوذُ بِكَ مِنْ حَرِّ النَّارِ، وَمِنْ عَذَابِ الْقَبْرِ
Translation 
O Allah, Lord of Gabriel and Michael, and lord of Israfel, I seek refuge in You from the heat of the hell fire, and from the torment of the grave.
Transliteration
Allaahumma rab-ba jibraa’eel wa meekaa’eel, wa rab-ba israafeel, a‛oodhu bi-ka min ḥar-rin naar, wa min ‛adhaabil qabr
